Some of the biggest names in music are gathering in Las Vegas this weekend for the 2026 iHeartRadio Music Festival, with BTS, Cardi B, Snoop Dogg, Benson Boone, Ciara and Zara Larsson among the stars taking over the stage.

The two-night festival is being held at T-Mobile Arena on September 18 and 19, with Ryan Seacrest returning as host and a lineup spanning K-pop, hip-hop, pop, rock, country and electronic music.

BTS leads a star-packed lineup

This year’s festival brings together artists from several generations and genres.

Alongside BTS and Cardi B, the full lineup includes Benson Boone, Ciara, Goo Goo Dolls, Kenny Chesney, Lainey Wilson, LE SSERAFIM, Major Lazer, Muse, Snoop Dogg, The Smashing Pumpkins, Weezer and Zara Larsson.

Rising singer Stella Lefty is also scheduled for a special performance.

The mix has become one of the defining features of the iHeartRadio Music Festival, where country stars can appear on the same bill as K-pop groups, hip-hop legends and alternative rock bands.

LE SSERAFIM makes festival history

The 2026 edition also brings an important K-pop milestone.

LE SSERAFIM is set to become the first K-pop girl group to perform at the iHeartRadio Music Festival when they take the stage on Saturday, September 19.

Their appearance comes alongside BTS, giving K-pop a particularly strong presence at this year’s event and reflecting the genre’s increasingly central position within the global mainstream music industry.

How to watch the festival live

Fans who are not in Las Vegas will still be able to follow the entire event from home.

Both nights will stream live on Disney+ and Hulu, beginning at 7:30pm PT / 10:30pm ET.

The festival will also be broadcast live through iHeartRadio stations across more than 150 US markets.

Streaming availability can vary by country, so international viewers should check their local Disney+ and Hulu services before the show begins.

Can you watch it for free?

For viewers in the US, there is also a potential free-trial option.

New DirecTV customers can access a five-day free trial on eligible streaming plans, providing another route to watch the festival without paying for a long-term subscription.

The Disney+ and Hulu bundle is also available directly, with the ad-supported package currently priced at $12.99 per month and the premium option at $19.99 per month in the US.

As always, prices, free trials and availability can depend on location and eligibility.

Las Vegas becomes the centre of pop culture for two nights

The festival is not limited to performances on the main stage.

This year’s iHeartRadio House of Music is also open outside T-Mobile Arena, with immersive experiences inspired by artists including BTS, Cardi B, Kenny Chesney and Zara Larsson.

The space is free to the public on both festival days from 4pm until 1am and includes interactive installations designed around the music and personalities of the performers.

More celebrity guests are heading to Vegas

The music lineup will be joined by a broad group of presenters and celebrity guests.

Confirmed names include Donny Osmond, Raven-Symoné, Jenna Dewan, Mario Lopez, Danielle Fishel, Taylor Hanson, Lele Pons, Val Chmerkovskiy and members of The Breakfast Club.

Lainey Wilson will also pull double duty, appearing both as a performer and among the event’s presenters.

One of the biggest music weekends of the year

The iHeartRadio Music Festival has built its identity around unlikely combinations and one-off performances rather than a single musical genre.

That approach is especially visible in 2026.

BTS and LE SSERAFIM represent global K-pop, Cardi B and Snoop Dogg bring hip-hop, Kenny Chesney and Lainey Wilson cover country, Muse and The Smashing Pumpkins bring alternative rock, while Benson Boone, Ciara and Zara Larsson add major pop moments.

With two nights of live performances, surprise collaborations and one of the most varied lineups on the festival calendar, Las Vegas is becoming the centre of global music for the weekend.

The 2026 iHeartRadio Music Festival takes place September 18 and 19 at T-Mobile Arena, with every performance streaming live on Disney+ and Hulu.
